SMITH, BOTH HYDROCARBON-BURN ER.

SPECIFICATION forming part of Letters Patent No. 404,804, dated June 4,1889. Application filed February 26, 1889. Serial No. 301,235. (Nomodel.)

To all whom it may concern.-

Be it known that I, l/VILLIAM SNEE, a citizen of the United States, anda resident of Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inHydrocarbonBurners; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification.

This invention relates to, hydrocarbonburners adapted to burn crudepetroleum for generating steam in boilers of locomotive or stationaryengines; and it consists in, the improved consti notion of the fire-boxand in the co1nbination,with the fire-box, of valves for feeding air tothe combustion-chamber, and thereby regulate in a simple and expeditiousmanner the amount of heat.

On the accompanying drawings I have shown my invention as applied to theboiler of a locomotive, showing the boiler and firebox of the same.

Figure 1 represents a longitudinal sectional View, 011 a vertical plane,of a locomotive boiler and fire-box, according to my improvedconstruction; and Fig. 2 is a View from the under side of the fire-box,showing the circular valves and the levers for operating the same.

Like letters of reference denote corresponding parts in both thefigures.

Reference being had to the drawings, the letter A designates the boiler,which is provided with the usual fiues B, of any approved constructionand arrangement.

0 is the fire-box, inside of which I place a combustion-chamber D of thepeculiar shape and construction shown in the drawings.

This combustion-chamber consists of a hood E, of a Width correspondingto the width of the fire-box and extending from one side of the same tothe other. I prefer to make this hood of iron or other suitable metal,with a hollow space inside, which is filled with fire-clay or otherrefractory material capable of withstanding intense heat. This hoodforms a crown or arch F immediately above the burner G, and is then bentin a down ward and forward direction, as clearly illustrated on thedrawings, extending toward the front part of the fire-box.

Below the forward part of this hood and in front of the burner is placeda deflector H, made of the same material as the hood proper andoperating in conjunction with the forward part of the same to forma'cont-racted mouth-piece, as shown at I. This deflector II also extendsclear across the fire-boxfrom one side to the other, thus forming, inconjunction with the hood, the dome-shapedcombustion-chamber D, providedwith the oblong outlet or mouth-piece I.

The burner (shown at G) may be of any approved construction adapted toburn crude petroleum, either by itself or in conjunction with a jet ofsteam The fuel is fed to it by means of a feed-pipe .I, provided with asuitable valve or valves, and bent at right angles, as shown at J, itsupper end being c011- nected to a suitably-located tank or reservoircontaining the liquid fuel. If the burner is designed to burnhydrocarbons mixed with steam, the steam-pipe may be convenientlylocated inside of the feed-pipe J, so as to heat the hydrocarbon as itpasses up into the burner. I desire the same to be understood, however,thatI do not limit myself to any particular type or construction ofburner, as

my invention consists not in the construction of the burner itself, butin the construction and combination of parts of the combustionchamberand air-valves.

The bottom of the combustion-chamber D is perforated, and covered on itsunder side by a circular disk K, having apertures 70 registering withthe apertures in the bottom of the combustion-chamber. This aperturcddisk K has a central opening through which pipe J is inserted, so thatsaid pipe Will form a spindle or journal for the disk, around which itmay be turned. The periphery of the disk is supported by and slides inan an-' nular flange L, fastened to the under side of the fire-box andoverlapping the under side of the movable valve-disk K.

The central part of disk K is provided with a downwardly-projectingsleeve or collar M, which turns upon thatpart of pipe J inserted throughit, and is provided with a lever N, projecting in front of the fire-box,and having a handle whereby it may readily be manipulated by the firemanor engineer in charge.

Another valve K, of precisely similar construction, is located in thebottom of the firebox immediately in front of the opening or outlet I ofthe combustion-chamber, and is manipulated by means of the handle orlever N. If desired, additional valves for regulating the supply of airto the fire-box may be located in the front wall of the latter, asindicated at O and P.

In some cases it may be desirable to provide the fire-box back of thecombustionchamber D with a transverse breast-wall Q, for the purpose ofdeflecting the products of combustion over the top of the same beforereaching the Ilues. This, however, is not essential.

The operation of this apparatus is as follows: After the oil has beenturned on and is ignited in the burner in the usual manner, the valve Kis so adjusted as to feed a sufficient quantity of air into thecombustionchamber to generate heat enough to vaporize the oil. After alittle while the hood E F will be raised to a very high temperature bythe combustion of the gases with which it is filled, and by now closingor partially closing the bottom valve K, at the same time opening valveK, the gas which is generated within the combustion-chamber, and thereinsuperheated to a temperature considerably beyond the explosion-point,will ignite on being supplied with air enough, through valve K, topermit of combustion. Thus a flame of in tense heat will issue from theoutlet I,which,

by impinging upon and curving around the dome F of theeombustion-chamber,will maintain the heat within said chamber, therebymaintaining a constant supply of gas from the burner. By judiciouslyregulating the supply of air through the valves K and K, and theauxiliary valves 0 and P when the latter are used, the temperaturewithin the fire-box may readily be regulated at will, and by closing allthe valves the fire will be we tinguished in a moment.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States 1. In a boiler-furnace provided witha firebox, the combination of the fire-box, the domeshaped hood withinthe same bent downwardly and forwardly at its front side, the deflectorarranged below the forward part of the hood, and the burner locatedbelow the arched top an d within the hood, substantially as and for thepurpose shown and set forth.

2. In a boiler-furnace provided with a firebox, the combination of theexterior fire-box communicating with the fines of the steamgenerator,the combustion-chamber located within the fire-box having an arched ordomeshapedtop and narrow mouth or outlet faci n the front end of thefire-box, the burner located within the combustion-chamber below itsarched top and back of its outlet, the air valve in the bottom of thecombustion-chamber encircling the burner, and the bottom valve in thefire-chamber outside of the comlnistion-chamber, but below the outlet ofthe same, substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoalfixed my signature in presence of two witnesses.
